Not as polished as Kurt's later works, but it's always interesting to see how the well-known mappers started out. It's certainly a good map, with balanced gameplay and the kind of interesting structures and height differences that marked the author's subsequent creations.

I liked it. All the secrets have some kind of clue, be it flickering light, adjacent torches, or something subtle like slightly different sector light (visible on ceiling). Even that one secret door in nukage sector has a pretty obvious entrance from the other side. More of a puzzler than a shooter style map. Only thing I couldn't figure out was how to get the plasma gun?...
